MAINTENANCE
4.1 Safety Matters
Risk of injury from electric shock!
Cleaning machines that are not disconnected from the mains can lead to serious injuries!
◎ Disconnect the machine completely from the mains.
◎ Remove the mains plug.
◎ Wait for 5 minutes until the capacitors have discharged.
ELECTRIC SHOCK can kill
◎ Turn the input power OFF at he welding power source before installation or changing drive rolls
and/or guides.
◎ Do not touch electrically live parts.
◎ When inching with the gun trigger, electrode and drive mechanism are “hot” to work and ground
and could remain energized several seconds after the gun trigger is released.
◎ Do not operate with covers, panels or guards removed or open.
◎ Only qualified personnel should perform maintenance work.
ITEMS REQUIRING NO MAINTENANCE
◎ Drive Motor and Gearbox - Lifetime lubrication
◎ Wire Reel Spindle - Do NOT lubricate shaft
ROUTINE AND PERIODIC MAINTENANCE
◎ BEFORE EACH USE -Check over machine and accessories for any obvious condition that may
prevent safe performance or operation, repair or replace items as necessary to correct any abnormal
condition.
AFTER 5 MINUTES OF WELDING OR WHEN SPATTER ACCUMULATES ON THE CONTACT
TIP:
◎ CLEANING TIP AND NOZZLE- With the power switch in the OFF position, keep the contact tip and
nozzle clean to avoid are bridging between them. Bridging can result in a shorted nozzle, poor welds and an
overheated gun. Hint: Anti-stick spray or gel, available from a welding supplier, may reduce buildup and aid
in spatter removal.
4.2 Daily maintenance
The power of the switching box and the welding machine should be shut down before daily checking (except
appearance checking without contacting the conductive body) to avoid personal injury accidents such as
electric shock and burns.
1) Daily checking is very important in keeping the high performance and safe operation of this welding machine.
2) Do daily checking according to the table below, and clean or replace components when necessary.
