OPERATION
Work Clamp
Electrode Holder
Only plug a TIG Torch or Electrode Holder into the
right Socket.
Only plug the work clamp into the left Socket.
To prevent serious injury and death: If the operator
is not holding the Electrode Holder, it must be
sitting on a nonconductive, nonflammable surface.
The Welder will immediately turn on when the Power
Switch is turned on.
Select the STICK with process select button.
1
Select the output current I (A) with sequencer
control button, turn the control knob to meet the
needs of the job. Higher amps for thicker material,
lower amps for thinner material.
Specify your Arc Force setting, the Arc Force
increases temporary the output current, used to
clear intermittent connections between the
electrode and the weld puddle that occur during
stick welding

OPERATION
Very little routine maintenance is necessary to keep
your TIG-225P running in top condition. No specific
schedule can be set for performing the following items;
factors such as hours of usage and machine environment
should be considered when establishing a maintenance
schedule.
Periodically blow out dust and dirt which may
accumulate within the welder using an air stream.
Inspect welder output and control cables for fraying,
cuts, and bare spots.
The fan motor has sealed ball bearings which require
no maintenance.

TROUBLESHOOTING
Observe all Safety Guidelines detailed throughout this manual
Poor work clamp connection
Start current is too low
Problems(Symptoms) Recommended Course of Action Possible Cause
Check and secure work connection
Increase start current
Poor starting
Oily or organic contamination on work
piece
Tungsten electrode may be
contaminated
Leaks in gas line or torch connection
Gas tank is near empty
Clean work piece
Grind to clean electrode
Check connection
Replace the gas tank
Black area along weld bead
Check for proper machine ground connection;
surrounding machines that generate hi-freq
also should be grounded properly
Output quits momentarily; gas
flow and hi-freq are also
interrupted
Pulser may be turned on inadvertently
Electrode may be too large for current
setting
Insufficient gas shielding
Contaminated gas or leaks in gas line,
torch, or connections
Turn Pulser off
Use smaller Tungsten
Adjust flow rate
Check gas line & connections
Arc flutters
Output shut off during welding Faulty Components, PC Boards or
Connections

Observe all Safety Guidelines detailed throughout this manual
Poor work clamp connection
Problems(Symptoms) Recommended Course of Action Possible Cause
Check and secure work connection
Poor starting
Stick electrode "blasts off" when
arc is struck
Electrode "sticks" in weld puddle
Current may be set too high for
electrode size
Current may be set too low for electrode
size
Arc force set too low
Adjust current
Adjust current
Access "STICK" function (see operation
section) and increase "ARC FORCE" setting
