General Safety Information
The WGW 300 is a high voltage piece of equipment. Always disconnect the power source before performing
service and maintenance to the unit. Never pull or carry welder by the power cord or electrical connection.
Always keep slack in extension cord while in operation to avoid damage to the power connection. Keep hands
and other body parts clear of heating wedge and elements when hot. Do not operate near flammable materials.
Do not apply flammable liquids to seam area. Allow unit to cool down for at least 5 minutes before putting back
into shipping/storage case. Protect unit from exposure to direct rainfall or standing water. Never attempt to weld
in standing water.
Intended Use
For additional product information please refer to the product data sheet. The WGW 300 has been manufactured
according to the latest technology and current safety regulations. However, improper use or abuse may lead to
hazardous conditions for the user or third party or damage to the unit.
Always have this manual handy at the location where the WGW 300 is being used so that it can be referred to
quickly and easily.
The technician assigned to operate this welder must have read through and become familiar with this manual
before starting work, particularly the section on safety.
Do not make changes or modifications to the WGW 300 relative to safety without contacting the manufacturer for
advice.
Maintenance
Maintenance, inspection and adjustment of the WGW 300 may only be carried out by qualified personnel.
Before removing or installing spare parts or performing other repair operations to the WGW 300, consult the
manufacturer for advice on proper procedures. This will help insure a safe and successful outcome. Always make
sure all screw connections are tight before attempting to operate the unit after maintenance or repair. Also make
sure all covers, guards, and other safety devices have been reinstalled before use.
Power Requirements
The voltage requirement of your WGW 300 hot wedge welder depends on voltage specified when ordered. WGW
300 will operate properly at 208VAC to 240VAC.
Note: The above operating voltage ranges refer to actual voltage at point of welder plug-in. In other words, the
voltage under load at the welder end of the extension cord. To measure voltage under load, connect the welder
to the extension cord and generator that will be used. Start the generator and turn both welder power switches to
the on position. While the number 1 indicator light on the temperature controller is illuminated and the wedge is
heating, separate the plug at the end of the welders power cord just enough to expose the prongs. Using a digital
voltmeter, measure the voltage under load between the hot and neutral prongs.
This procedure should only be performed by a qualified electrician.
Generator Recommendation
If using house power from a building circuit, please contact the manufacturer for advice on plug and cord

5
configuration. In-field generators should be rated for at least 3500 watts; however, a rating of 5000 watts or more
is recommended in order to obtain the best welder performance and temperature control. As a rule, the higher
the wattage of the generator, the better the performance of the welder. Keep in mind that the length and wire
gauge of the extension cord being used, combined with the capacity of the generator, will ultimately determine the
operating voltage reaching the welder.
Extension Cords
Extension cords should be at least 3 x 1.5m2 with ground connections.

Material Set-up
The WGW 300 is designed to weld a wide range of material types and thickness from very thin PE and PP to very
thick materials such as 1.5-2.5mm HDPE. The WGW 300 uses a spring-loaded upper contour roller system and
“floating” wedge design that allows the operator to weld several different thicknesses of material without resetting
the adjustments. However, for best results on all materials, the following set-up procedure can be used.
Important! Unit must be cooled down before attempting adjustments.
Please refer to the parts identification photos as instructed throughout the set up procedure.

Set-up Nip Pressure Adjustment:
Adjustment Location:
The nip pressure adjustment is located between the nip lever and upper nip arm; it is a hex shaped turnbuckle
style nut (#6, Figure 1).
The correct amount of nip pressure is needed to get a good weld. It is also important that the nip rollers are
providing enough traction to keep the WGW 300 from “burning out”. This can happen when the nip rollers lose
traction and spin on the material, causing the WGW 300 to stop in the seam and burn a hole in the material.
Note: Pressure Adjustment for thin material and geotextiles:
These materials require less nip pressure. Too much pressure can cause the material to perforate at the edge of
the seam causing a “zipper” effect.
• Make sure the heating wedge (#14, Figure 1) is in the disengaged position.
• Turn the nip pressure adjustment hex nut clockwise while looking down from above several turns, raising the
nip arm up to give a fresh starting point for this adjustment. (Loosen set screw(s) on hex nut first if present to
avoid damaging threads on eye bolts)
• Place one end (one thickness) of your adjustment material between the nip rollers and into the unit about 1”
inch. Engage nip rollers by pushing down on the nip lever until it has “clicked” into place and is held in position
by the lock pin. At this point the material should move around freely between the nip rollers.
• Turn the hex nut (#6, Figure 1) counter clockwise until the nip rollers begin to pinch down on the material and
you cannot turn the nut by hand anymore. This zeroes the adjustment.
• Disengage nip rollers and turn the hex nut counter clockwise one full rotation.
• Insert the adjustment material (the opposite end of the fold, two thicknesses) between the nip rollers and
engage nip rollers together until the lock pin clicks into its detent as shown on the Figure 1. Check pressure
by attempting to move the material side to side. If you are able to move the material or pull the material
straight out without the nip rollers turning, disengage the nip pressure and turn adjustment nut (#6, Figure 1)
counter clockwise ¼ turn at a time until the desired pressure is reached. Remember to tighten the set screw(s)
on the adjustment nut after you have completed adjustment of the nip pressure to prevent the pressure from
backing off while welding.
Note: When the nip pressure adjustment is set correctly, engaging the nip pressure lever should take some effort
but it should feel like a smooth motion. Again, it is important that you are getting enough traction to avoid burning
out and at the same time providing enough nip pressure to create a good weld. Keep in mind that the thicker the
material being welded and especially textured material, the greater the pressure should be.

Set-up Upper Contour Roller Configurations:
Location:
The upper contour roller (#15, Figure 2) assembly is located above the heating wedge and is fixed to the bottom
of the nip arm assembly.
Note: There are two types of springs, one that the roller axle mounts to and one that is used as a stiffener or “back
up spring”. There are also two mounting locations on the mount plate, one for the rear roller set (closest to the nip
rollers) and one for the front roller set (furthest from the nip rollers).
Removing-upper contour roller assembly:
• Remove screw from the end of the shaft that the material guide plate pivots on, then slide material guide off of
shaft and set aside.
• Remove the two Phillips head screws that attach the upper contour roller assembly mount plate to the nip arm
and remove contour assembly from the unit. You may need to move the heating wedge fore or aft for access
with screwdriver.

• With the nip pressure lever in the up position and the wedge in the disengaged position, insert the adjustment
material that you cut earlier from the template into the WGW 300 as shown in Figure 4 above:
• Insert just enough in so that about 70mm of material is protruding out of the nip rollers from the point where
the nip rollers pinch down on the material. Slide the wedge to its engaged position until it locks into its detent.
Then lock the nip pressure lever down on to the material.
• With a Phillips screw driver remove lower frame chain cover (#7, Figure 7) to expose the lockdown bolt for the
front lower contour roller.
Note 1:
• Please pull out rubber plugs before adjusting the both rollers (#12 and #13 in Figure 4) and insert them back to
original position after adjustment finished.
• Using a 6mm Allen wrench, loosen the lockdown bolt and then temporarily adjust the front lower contour roller
down, clockwise, away from the wedge using a 4mm Allen wrench on the end of the roller (this will give you a
fresh starting point and you will make a final adjustment on this roller later).
• Using a 13mm open end wrench, loosen the lockdown bolt (hex head) for the rear lower contour roller (#13,
Figure 4). You can now adjust the height of the wedge by adjusting the rear lower contour roller up or
down with a 4mm Allen wrench at the end of the roller. Once the desired position has been achieved, tighten
the lockdown bolt (hex head) then check the adjustment again to make sure it did not move when tightened.
• The most important adjustment is the positioning of the wedge in relationship to the lower nip roller (#17,
Figure 4). The distance between the lower tip of the heating wedge and the lower nip roller should be
slightly more than the thickness of the material you will be welding. The distance is set by adjusting
the rear lower contour roller (#13, Figure 4) up or down.
Set-up Lower Contour Roller Adjustment
Location:
The lower contour rollers (#12, #13, Figure 4) are located below the heating wedge and are mounted to the lower
frame directly in front of the lower nip roller. For this adjustment you will need a 13mm open end wrench and a
4mm and 6mm Allen wrench.
Figure 4

Note 2: When adjusting the lower contour rollers (#12) and (#13) rotate them both to the right (counterclockwise)
and up so that in their adjusted positions the rollers are closest to the nip roller (#17). Also because the rear
contour roller (#13) is forcing the wedge up against the upper contour roller spring tension, you may notice the
roller will still spin with your fingers. This is normal. The amount of resistance of the roller when turning it with
your fingers does not matter.
Warning! If the rear lower contour roller is adjusted too high, there will not be enough clearance for the top sheet
to travel through the welder and it will be pinched between the top of the heating wedge and the upper nip frame.
This will result in loss of welding nip pressure and an inconsistent weld.
• Figure 4 until it just comes in contact with the material. The roller should have a slight amount of resistance as
you rotate it. If you adjust it to tight it will rock the wedge and change the rear roller (#13) adjustment.
Note 3: If you are setting up the WGW 300 to weld thin material or in very hot ambient conditions the front
contour roller (#12) adjustment should be set very loose or backed off completely to reduce material dwell time (over
heating material) and minimize the possibility of burn outs.
• Step 4: Set-up Wedge Fore/Aft Adjustment
The fore/aft adjustment sets the limit of travel of the heating wedge in its fully engaged position. In other
words, how close the tip of the wedge is to the nip rollers. If the tip of the wedge is too close to the nip rollers
they will pinch down on the wedge when pressure is engaged, reducing the amount of nip pressure on the
heated material. This can also cause damage to the tip of the wedge when running out of the end of the seam.
Adjustment procedures for lock mount assemblies (Figure 5):
• With the material set-up piece in place and with the nip lever and wedge engaged as shown on Figure 5, use
a 5mm Allen wrench to loosen the wedge mount bolt that connects the wedge hex mount to the wedge slide
lock mount (#18, Figure 5).
• Using a 3mm Allen wrench, loosen the two lock screws that hold the lower piece of the assembly to the upper
piece. You will need to insert the 3mm Allen wrench between the cartridge heater lead wires to access one of
the screws.
• Move the heating wedge forward or backward (left or right) so that there is plenty of clearance between the
tip of the wedge and the upper and lower nip rollers. When adjusting WGW 300 for welding HDPE the
tip of the wedge should have the same clearance as shown in Figure 4.
• Tighten lock screws to set adjustment. Re-check all adjustments to make sure they are correct before
disengaging nip lever and wedge and removing material set-up piece.

Power Up
Connect the WGW 300 power cord to power source making sure that the voltage is correct for the model of
welder you have.
Flip the main power toggle switch (#1, Figure 6) to the “on” position (up). The main power switch is located on
the right of the control box, below the front handle. After a 3 second delay, the temperature control unit (#5,
Figure 6) located on top of the control box should light up and display current wedge temperature.
Turn on the drive motor with the motor switch (#3, Figure 6), located on the top of the control box. It is
recommended that the drive motor remain on at all times while the welder is plugged in. This helps to eliminate
hot spots on the nip rollers and makes starting a weld quicker and easier.
Setting Wedge Temperature
• OMRON Controller (5 button style)
Temperature controller has a dual display. The current wedge temperature set point is displayed on the right side
of the display. The actual wedge temperature is displayed on the left side of the display.
To adjust the wedge temperature set point, press the up arrow button to increase the set point or the down arrow
button to decrease the set point. Flip the heating switch (#4, Figure 6) to the "on" position, heating start to work
immediately.
Setting Weld Speed
To set weld speed, use the knob directly (#3, Figure 6) located on top of control box, next to temperature control
unit. Please refer the chart on the top of control box to get the correct speed value.

Starting a Weld
To start a weld, you must first make sure that the material to be welded is set at the proper overlap. The optimum
overlap is 12.7-15.2cm for field welds.
Start the loading process with the nip lever in the “up” or disengaged position, the heating wedge in the
“forward” or disengaged position (Figure 8), and the motor on with the nip rollers turning.
First, peel back the top sheet to expose the bottom sheet. Load bottom sheet of the material into welder, between
both lower contour rollers and the bottom of heating wedge, then between the two nip rollers.
Second, insert the top sheet into the welder, between the upper contour roller(s) and the top of the heating wedge,
and then between the nip rollers. You may need to roll the welder forward and backward a little for both sheets to
settle into the welder.
Third, pull out on the wedge lock handle and slide wedge toward nip rollers until the lock pin slides off the end on
the slide rail. Make sure wedge is completely engaged before continuing.
Fourth, engage nip rollers by pushing the nip pressure lever down until it “clicks” and is locked in position. At
this time the welder should be moving and welding on its own. If the nip rollers are spinning on the material
and burning a hole, quickly disengage nip rollers, roll the welder down the seam a few more inches, past the
overheated area, and engage again.
Ending a Weld
Just as the welder is about to run out of the end of the seam, disengage nip rollers, slide welder out of the seam,
and then disengage wedge. At this time it is a good idea to tip the WGW 300 up onto the front handle, raising the
back of the unit, to prevent a hole being melted in the material from heat radiating from the wedge.
Shut-Down
To shut down the WGW 300, simply turn main switch to the “off” position or unplug unit. After 5-10 minutes,
place unit in shipping/storage case provided with welder.

• 确认焊锲（14）在待机位置。否则，用手柄把焊锲回拉，后退到待机位置。
• 顺时针方向转动压力调节螺柱（6）数圈，抬起压力臂准备开始调节。（先把螺柱上方的
锁定螺丝松开，避免损毁球头螺丝的螺纹。）
• 取一段待焊接的材料，把一端（一层材料）放入压力轮之间，约 3cm。按住压力杆下压
到正确的位置，扣入锁定销定位。此时，材料可以不受阻力的在压力轮中间移动。
• 逆时针转动螺柱（6），直到压力轮下压接触到材料并且无法再用手转动为止。
这是调节压力的归零步骤。
• 抬起压力臂，脱开压力轮。再按照逆时针转动一整圈。
• 再次在压力轮之间放入待焊接的材料（把材料对折再放入，两层材料厚度），直到
锁定销弹入孔位。拖动膜材，确认压力是否足够。如果能够拖动材料，或者直接把材
料从压力轮中抽出，则需要松开压力轮，把螺柱再沿逆时针方向转动四分之一圈。在设定
好压力之后，记得把锁定螺丝拧紧，防止在焊接时压力轮被顶开而失去压力。
注意：正确地设定压力后，按下压力杆会有些费力但是仍有顺滑的感觉。重申，足够的牵引
力非常必要，以避免烧毁材料。请谨记：材料越厚，尤其是糙面膜材，压力应当越大。
上导轮位置：上膜材导轮（15）位于热锲上方，安装于压力臂的底部。改变弹片的数量，会
改变导轮的松紧度。
注意：WGW 300 出厂配置如下图，适用于 1.5-2.5mm 的 HDPE 膜材焊接。除非需要更换上
导轮，请忽略以下步骤。

位置：下膜材导轮（12) (13) 位于热锲下方，直接安装在支架上。
需要使用 4mm 内六角扳手，6mm 内六角扳手和 13mm 开口扳手来调节。
• 抬起压力臂，如图放入待焊接的材料。
• 把材料对折后塞入焊接机，放于热锲的上下两端。放入足够的长度（约 7cm）：确保把
热 锲向前推送到焊接位置，并把压力轮下压后，膜材完全接触到 2 个下导轮。
• 取下螺丝，移除下链条护盖 (7)，露出前侧下导轮 (12) 的固定螺丝。
• 使用内六角扳手松开固定螺丝，把下导轮向下转动，远离压力轮。（ 后设定到最佳位
置后再固定）
• 用 13mm 开口扳手松开后侧下导轮（13）的固定螺丝。松开后，可以通过抬高或降
低后侧下导轮来调整热锲的高度。当达到合适的位置时，把固定螺丝锁紧。按下压力臂，
确认螺丝没有松动。
设定下膜材导轮：
把挡板固定轴上的螺丝松开，取下挡板。
松开固定上膜材导轮于压力臂上的 2 颗螺丝，把导轮从焊接机上取下。过程中，需要前后调
整热锲的位置。
拆卸上膜材导轮：

• 把前侧下导轮（12）向右上方调整（逆时针方向），直到和膜材接触。此时，转动导轮时
略有阻力。如果拧太紧，前侧下导轮会挡住热锲并改变后侧下导轮的设定位置。
注意：
调整导轮 12 和 13 时请先拔出白色硅胶堵头，调整完毕后再塞回原位置。
最重要的是，热锲和压力轮（16）的相对位置。热锲的尖端和压力轮的距离要比膜材的厚度
略大。通过调整后侧下导轮（13）的上下来调整距离。
当把下导轮（12) (13)同时按逆时针方向转动时，调节下导轮的高度。此时的下
导轮会非常靠近下压轮（16）。又因为后侧下压轮把热锲挺起到上压轮弹片，你会发现能够
转动下压轮。这是正常现象，而转动的阻力大小无关紧要。
警告！如果后侧下导轮 (13) 的位置设定过高，会导致热锲上方的间隙不足，上层膜材被夹住
无法穿过焊接机。这会导致焊接压力下降，焊接不稳定。
如果焊接薄材料，或者高温下作业时，前侧下导轮应该设定得更加松甚至脱离材料。这样可
以减少材料的接触时间（防止材料过热）尽可能避免烧穿材料。
设定热锲的前后位置：
设定热锲在焊接位置时，压力臂下压后的行程限制位置。松开锁定座（18）的螺丝，把热楔
调整到合适位置后重新锁定。换言之，设定热锲尖端和压力轮之间的距离。如果尖端太靠近
压力轮，下压时压力轮会夹住热锲尖端，造成焊接压力下降。另外，焊接结束后，焊接机自
动从膜材中驶出，压轮会把热锲压坏。

先确认电压、电线规格和长度，再接通焊接机电源。
打开电源开关（1），约 3 秒后，温控仪（5）显示出当前的热锲温度。
打开马达开关（2），推荐在焊接机开机时，马达始终在启动状态。这样做，能避免
压力轮的某一个位置过热，在开始焊接时更加顺畅。
设定热锲温度：
WGW 300 装配的温度控制器在出厂前经过调试。在开机后，通过温控仪的“上︿”和“ 下 ﹀”
按键设定温度。温度控制器能显示设定值和实际值。设定所需的温度后，打开温度开关 (4)，
焊接机开始迅速加热。
设定焊接速度：
使用旋钮直接调节速度。请参考在面板正面的速度值对照表，获得合适的速度。
开始焊接
开始焊接前，必须把膜材放入合适的交叠位置。工地现场理想的交叠宽度是 12~15cm。
开始焊接前，压力臂抬起，处于张开状态；热锲处于待机位置；马达打开，压力轮
持续转动。
首先，拨开上层的膜材，露出下层的材料。把下层材料放入焊接机，放在下导轮和热锲底部
之间，并且向前达到压力轮。

然后，把上层材料放入焊接机，放在上导轮和热锲顶部之间，并且向前达到压力轮。需要前
后挪动焊接机，把两层材料放置到位。
第三步，拔出热锲的定位手柄，把热锲滑向压力轮的方向，直到定位手柄在滑轨另一端弹入
定位槽。确认热锲已经固定后，继续下一步。
最后， 把压力臂按下，直到定位销弹入凹槽，压力锁定。此时，焊接机开始自动行走并焊接。
如果压力轮夹住材料，把材料烧穿，请迅速打开压力臂把焊接机向后拖动约 10cm，离开过
热的区域重新按下压力臂，开始焊接。
焊接结束
在焊接机快要从膜材末端驶出时抬起压力臂，把焊接机从焊缝处拖出，再把热锲退回到待机
位置。向上提起前把手，把机器略微抬高，能有效避免热锲把材料熔融。
关机
直接关掉电源主开关 ( 如图 ) 或拔掉电源线插头 ( 仅在紧急情况 )。约 5~10 分钟后，再把设
备放入包装箱。
