when installing, operating and servicing the product.
1.2. PRODUCT INTRODUCTION
KEMPPI MTP MIG/MAG guns for manual welding are designed for
demanding professional use. They are suitable to be used in all MIG
units equipped with Euro adapter.
1.3 OPERATION SAFETY
Please study these Operation safety instructions and respect them
when installing, operating and servicing the machine.
Welding arc and spatters
Welding arc hurts unprotected eyes. Be careful also with reecting arc
ash. Welding arc and spatter burn unprotected skin. Use safety gloves
and protective clothing.
Danger for re or explosion
Pay attention to re safety regulations. Remove ammable or explosive
materials from welding place. Always reserve sufficient fire-fighting

The gun is equipped with spiral liner for welding normal steel wire.
Before connecting the gun, make sure that its wire liner is according to
recommendations for the welding wire in question.
Set the snap connector carefully at its place so that the control connectors
will not get damaged. Tighten the snap connector carefully in order to
avoid voltage losses. Loose connection will heat the gun and the feeder
unit. Control tightness of connection daily.
equipment on welding place. Be prepared for hazards in special
welding jobs, eg. for the danger of fire or explosion when welding
container type work pieces. Note! Fire can break out from sparks even
several hours after the welding work has been nished!
Mains voltage
Never take welding machine inside a work piece (eg. container or truck).
Do not place welding machine on a wet surface. Always check cables
before operating the machine. Change defect cables without delay.
Defect cables may cause an injury or set out a fire. Connection cable
must not be compressed, it must not touch sharp edges or hot work
pieces.
Welding power circuit
Isolate yourself by using proper protective clothing, do not wear wet
clothing. Never work on a wet surface or use defect cables. Do not put
MIG gun or welding cables on welding machine or on other electric
equipment. Do not press MIG gun switch, if the gun is not directed
towards a work piece.
Welding fumes
Take care that there is sucient ventilation during welding. Take special
safety precautions when welding metals which contain lead, cadmium,
zinc, mercury or beryllium.

2. CONNECTING THE GUN

The amount of use and working environment should be taken into
consideration when planning the frequency of maintenance of MIG
guns. Careful use and preventive maintenance will help to ensure
trouble-free operation and long lifetime for the gun.
Due to high temperatures and wear, the welding end of MIG gun
requires most maintenance but also condition of other parts should be
checked regularly.
Welding end
• Remove welding spatter and check condition of insulations, contact
tip and gas nozzle. Replace damaged and worn-out parts. Use only
original Kemppi spare parts.
• Check condition of insulations. Replace damaged insulations immediately.
• Check that in the discharge holes for shielding gas there is no spatter
or dirt.
• Use the gun in a proper way:
- Do not remove welding spatter by hammering the gun against the
work piece!
- Do not use sharp tools, because damaging of surfaces will increase
stickening of spatter!
- Do not bend neck body of gun or fasten the gun from neck body
against bench etc., for it may cause destruction of the neck!
- Do not use the gun as hammer!.
3. USE AND MAINTENANCE
EN
OPERATING MANUAL
English
5
• Before driving the wire into gun check that the wire end is straight at
a length of approx. 200 mm and the tip blunt (le if necessary). A
sharp wire tip may damage wire liner and contact tip of gun.
• Watch out for wire sticking out from welding end of gun. Do not direct
the gun towards people or work piece, instead make sure that the wire
comes freely out in the air.

4. OPERATION DISTURBANCES
The most common operation disturbances are as follows:
Welding wire does not run smoothly or wire is sticking in the wire liner (arc length varies,
you can feel shaking in the handle):
• Wire liner is dirty or blocked-up. Clean with compressed air. Replace
wire liner if necessary.
• Wrong wire liner or contact tip. Make sure that wire liner and contact
tip are according to recommendations for the welding wire in question.
• Contact tip has heatened up too much.
• Contact face of contact tip is damaged due to spatter or sparking
caused by impurities. Replace contact tip.
• Gun cable has too sharp bends, straighten.
• Welding wire has a lot of dirt, rust or bends etc., which increases
friction and results in contact disturbances.
• Check operation of the wire feed unit. Check that drive roll size and
type are suitable for wire in question. Check that drive roll pressure is
not too low or too high.
Gas shielding is bad(weld pool "is boiling", arc is unstable):
• On inner face of gas nozzle or in contact tip and contact tip holder
there is too much welding spatter; clean.
• In discharge hole for shielding gas there is spatter or other dirt; clean.
• There are impurities in shielding gas (moisture, air).
• There are impurities in base material (rust, base coat, grease).
• Pressure gathered in long gas hoses will cause a great ow of
shielding gas at welding start, which may cause turbulence or mixing
of air into shielding gas. The reason may also be a faulty or a faulty
regulated relief valve which lets too much pressure into gas hoses.
• Flow of shielding gas is too small or too big (causes turbulence). Use
in short arc range a ow of 8 - 15 l/min, in hot arc range 10 - 20 l/min.
EN

Gun cable
• Clean wire liner when replacing wire reel, or more often.
• Check daily that insulations of handle and gun cable are undamaged.
• Check that there are no sharp bends in gun cable.

• Distance of gun to work piece is too long. In short arc welding keep
the gas nozzle at a distance of 10 - 15 mm and in hot arc welding at a
distance of 15 - 30 mm to work piece.
• Angle of tilt of gun is too big.
• There is too much draught at welding place.

2. 安装连接焊枪
焊枪配置有配合一般钢焊丝的螺旋送丝管。连接安装焊枪之
前，确保送丝管适合所选的焊丝，如有疑问，请参照推荐信息选用
送丝管。
仔细将快速锁紧扣安装到位可以有效防止控制连接器损坏。确
保快速连接扣锁紧可以避免电压损失。松动的连接将使焊枪和送丝
机温度升高。每天检查连接器确保锁紧。
焊接区域存放足量的消防设备。特殊焊接工作需要做有针对性的准
备，例如焊接容器类工件需要特殊的防火防爆措施。注意！焊接工
作完成之后数小时之内，焊接火花也可能引起火灾。
电源电压
严禁将焊机放置在焊接工件内部（例如集装箱或卡车）。严禁
将焊机放置在潮湿的表面上。每次开启焊机前，检查电缆。及时更
换有问题的电缆。存在缺陷的电缆可能造成损伤或引发火灾。切勿
挤压电缆，并防止焊接电缆被尖角划伤和接触高温物体。
焊接电路
穿着适当的防护衣将自己与焊接工件电隔离，不要穿着潮湿的
衣服。不要在潮湿的表面进行焊接操作或使用存在缺陷的电缆。严
禁将MIG焊枪或者焊接电缆放置在焊机或者其他电子设备上。MIG
焊枪没有直接对准工件时，不要按压焊枪开关。
焊接烟尘和废气
请保持焊接区域充足良好的通风。当焊接金属包含铅，镉，
锌，水银或者铍时，请进行有针对性的特殊防护。

3. 使用及保养
制定MIG焊枪维护保养计划时，应将使用频率以及工作环境等
因素考虑在内。仔细的使用以及定期的维护保养将有益于确保焊枪
的正常工作和延长使用寿命。
由于高温和磨损，MIG焊枪的前端需较频繁的维护和保养，但
是其他组件的状态也需要定期检查。
焊枪前端
• 去除焊渣并检查绝缘套，导电嘴和喷嘴的状态。及时更换损坏
或磨穿的部件。请使用Kemppi原装配件。
• 检查绝缘套的状态，及时更换有损部件。
• 检查保护气体出气口是否有焊接飞溅或残渣。
• 正确使用焊枪。
- 不要在工件上方捶打焊枪的方式去除焊接飞溅。
- 不要使用尖锐的工具，表面的划伤将加剧焊接飞溅的沉积。
- 不要试图弯动焊枪鹅颈或利用夹紧鹅颈的方法将焊枪锁紧在
工作台上，这样将有可能直接损坏鹅颈。
- 不要把焊枪当锤子一样敲打。
焊枪电缆
• 每次更换焊丝卷时，清理焊接软管，或者更频繁的清理。
• 每天检查焊枪手柄和焊枪电缆的绝缘性能，观察其是否完好无损。
• 确保焊枪电缆没有急弯。 5
将焊丝穿入焊枪前，保持大概200毫米长度的焊丝笔直，并且其
顶端没有尖角 （如果必要，撮平尖角）。如果焊丝有尖角，将划伤送
丝管内部和导电嘴。
将焊丝送出焊枪，密切关注焊丝从焊枪前端自由伸出，送丝过
程中，不要直接将焊枪指向人或工件。

4. 操作故障诊断
下列信息为最常见的故障诊断方法：
送丝不畅或焊丝粘在送丝管上（焊弧不稳，操作者能感觉到手柄
内部振动）:
• 送丝管内有杂质或堵塞。使用压缩气体吹风。如果需要请进行更换。
• 焊丝和导电嘴不匹配。如有疑问，请参照推荐信息选用适合所
用焊丝的导电嘴。
• 导电嘴过热。
• 导电嘴的接触面由于焊渣或电火花造成损害。更换导电嘴。
• 焊枪电缆有急弯，请伸直。
• 焊丝有杂质，灰尘或尖角等。这些情况会引起送丝摩擦和接触
不良。
• 检查送丝单元。请检查送丝辊的沟槽尺寸是否和所用焊丝相符。
请检查送丝辊的压力，不要过大或者过小。
焊弧气体不稳定 （焊池沸腾，焊弧不稳定）
• 喷嘴或者导电嘴和导电嘴座内部有太多的焊渣，请清理。
• 保护气体的排气孔有焊渣或者其他渣滓，请清理。
• 保护气体有杂质（湿气，空气）。
• 基础材料有杂质（生锈，表面镀涂层，油脂）。
• 气管聚集过大的压力将使焊接开始时气流紊流或空气掺入。这
或许是由于没有正确调节减压器或减压器损坏引起的。
• 保护气体的气流过小或过大（引起气体紊流）。短弧焊接气流
一般在8-15 升/分，热弧焊接气流一般在10-20升/分。
• 焊枪与工件之间的距离过大。短弧焊接工件与焊枪之间的距离
保持在10-15mm之间，热弧焊接保持在15-30mm之间。
• 焊枪与工件之间的焊角过大。
• 焊接区域内通风气流过大。
